other countries for sanitary purposes, we do not follow our own 
precepts. It is a fact that comparatively very few Eucalypts are 
artificially planted in Australia, and yet most of its towns are like 
other towns in having low-lying, damp portions, and typhoid fever 
carries off a terribly sad proportion of their population. It is also 
a fact that the orthodox method of improving (?) land is to fell 
the trees (generally Eucalypts) which grow upon it. In preparing 
suburban land for purposes of sale it is usually the object to 
eradicate every trace of vegetable growth, and the idea of leaving 
say one Eucalypt to each allotment for the purpose of desiccating 
the ground seems never to be thought of. 
Baron Mueller attributes the salubrity of Eucalyptus regions 
to the following causes:—1. Their ready and copious absorption 
of moisture from the soil. 2. Their corresponding power of 
exhalation, much greater than that of many other kinds of trees. 
3. Their evolution of a peculiar, highly antiseptic, volatile oil. 
4. The disinfecting action of the fallen leaves on decaying organic 
matter in the soil. Eucalyptus leaves create no noxious effluvia 
by their own decomposition. 
E. globulus has been introduced experimentally in India, in 
the Nilgiris and Punjab. In the former hills the growth has been 
oft. girth in 20 years. (Brandis.) The wood of a tree grown on 
the Nilgiris, 18 years old and gsft. high, is grey, with darker 
streaks, and moderately hard. Pores moderate-sized, round, 
frequently arranged in groups or in radial or oblique lines. 
Medullary rays fine, very numerous, the intervals between the rays 
smaller than the diameter of the pores. Pores marked on a 
longitudinal section, and medullary rays visible as narrow bands 
on a radial section. 
Mr. Gass found in the Newman plantation, then five to six 
years old, an amount of material of 152 tons per acre, and Colonel 
Beddome is of opinion that the best treatment of Eucalyptus 
plantations, so as to get the greatest profit, will be to cut for 
coppice every five or six years, obtaining at the cuttings at least 
100 tons per acre. (Gamble, Afanual of Indian Timbers.) 
The timber of Z. globulus is of a rather pale colour, hard, 
heavy, strong, and durable, more twisted than that of 2. odligua,
